Orthogonality is a condition where two vectors are perpendicular to each other.

• Orthogonality is a property of vectors in a Euclidean space.

• Two vectors are orthogonal if their dot product is zero.

• Orthogonality is used in various mathematical fields such as linear algebra and calculus.

• Examples of orthogonal vectors include (1,0) and (0,1) in a 2D plane, and (1,0,0) and (0,1,0) in a 3D space.

The director circle is the locus of the centers of all circles that are tangent to two given circles.

• The equation of the director circle can be found using the equation of the given circles.

• The center of the director circle is the midpoint of the line joining the centers of the given circles.

• The radius of the director circle is half the difference of the radii of the given circles.

• The equation of the director circle is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center o...read more

Proto-oncogenes are present in all cells.

• Proto-oncogenes are normal genes that regulate cell growth and division.

• They can be found in all cells of the body.

• Mutations in proto-oncogenes can lead to their activation and transformation into oncogenes, which can cause cancer.

• Examples of proto-oncogenes include c-Myc, Ras, and Bcl-2.

Currently, there is no scientific evidence to suggest that any organism has self consciousness.

• Self consciousness is a complex concept that is difficult to define and measure.

• While some animals exhibit behaviors that suggest they may have some level of self awareness, such as recognizing themselves in a mirror, this does not necessarily indicate true self consciousness.

• Research in this area is ongoing and there is much debate among scientists about which organisms, if any, po...read more

Formen Ovale is a small hole in the fetal heart that allows blood to bypass the lungs.

• Allows blood to bypass the lungs

• Closes after birth

• Helps in fetal circulation

• May cause complications if not closed properly

Zymogens are inactive enzymes that require activation by cleavage of one or more peptide bonds.

• Zymogens are also known as proenzymes.

• They are synthesized and stored in an inactive form to prevent damage to the cells that produce them.

• Activation of zymogens occurs through proteolytic cleavage, which removes inhibitory peptides and exposes the active site.

• Examples of zymogens include trypsinogen, chymotrypsinogen, and prothrombin.

• Zymogens play an important role in regulating en...read more
